When drafting an email, which aspect is most likely to ensure proper formatting?

Using bullet points and paragraphs in an email is essential for ensuring proper formatting because it enhances readability and clarity. Well-structured emails help the recipient quickly understand the main points and follow the flow of information. Bullet points break down information into digestible sections, making it easier for readers to scan and find important details. Similarly, organizing content into clear paragraphs helps separate distinct ideas, allowing for a more organized presentation.

The other choices may not contribute to proper formatting in the same way. While minimizing the use of images can ensure that an email loads faster and appears more straightforward, it doesn't directly affect the textual presentation. Pasting from word processors can lead to formatting issues, as different programs may not translate formatting consistently. Sending an email without proofreading is likely to result in mistakes and confusion, detracting from the overall professionalism and effectiveness of the communication. Therefore, using bullet points and paragraphs is the most effective approach to achieving proper formatting in emails.
